Magnetic permanent wave fastener

ABSTRACT

A permanent wave rod for waving hair having a plastic cylindrical member on which the hair is wound and a stretchable, flexible band secured at one end to one end of the cylindrical member. A cap including magnetic material is connected to the other end of the flexible band, and magnetic means is mounted in the opposite end of the cylindrical member. When moved into position, the cap means is locked to the end of the cylindrical member by the proximity to the magnetic means, thus stretching the flexible member lengthwise over the full length of the cylindrical member to hold the hair in place.

MAGNETIC PERMANENT WAVE FASTENER FIELD OF THE INVENTION This invention relates to permanent wave rods, and more particularly, is concerned with a magnetically latched hair restraining strip.

BACKGROUND OF THE INVENTION The use of permanent waving rods for styling of hair is well known. In conventional permanent wave rods, a plastic cylindrical member is used to roll the hair while the hair is wet, such as from a permanent waving solution. To keep the hair from unwinding from the rod, a retaining device, such as a flexible band, is provided having one end permanently attached to one end of the rod. the other end of the retaining band is connected to a cap or plug which can be inserted in the other end of the rod, thereby stretching the retaining band lengthwise of the rod, the stretched band retaining the hair wound on the rod in place.

Conventional permanent waving rods of this type are awkward to use because the flexible band must be stretched to insert the cap in the end of the rod, the resilience of the stretched hand then holding the cap in place. The beautician operator must hold the rod in place with the hair wound on the rod and at the same time stretch the band and insert the cap into the end of the rod, all this while the hair, the operator's hands, and the permanent wave rod are all wet and slippery from the permanent waving solution.

SUMMARY OF THE INVENTION The present invention is directed to an improved permanent waving rod in which the free end of the retaining band is secured in place to the other end of the permanent wave rod by a permanent magnet retainer cap that holds itself in place. The retaining band does not have to be under tension to hold the cap in place, thus making it much easier for the operator to manipulate the cap into latching position. In brief, the permanent wave rod of the present invention comprises a cylindrical member of plastic, or the like, on which the hair is wound. An elongated flexible retaining member is secured at one end to one end of the cylindrical member. The other end of the flexible retaining member terminates in a cap which includes magnetic material. Magnetic means mounted in the opposite end of the cylindrical member attracts the cap to the end of the cylindrical member to hold the retaining member in positin to clamp the hair against the cylindrical member.

BRIEF DESCRIPTION OF THE DRAWINGS For a more complete understanding of the invention, reference should be made to the accompanying drawing, wherein:

FIG. 1 is a side view of the permanent wave rod;

FIG. 2 is a partial sectional view of one end of the permanent wave rod; and

FIG. 3 is an exploded view of the end of the permanent wave rod.

DETAILED DESCRIPTION Referring to the drawing in detail, the numeral indicates generally a permanent wave rod which includes an elongated cylindrical body 12 with outwardly tapered end portions 14 and 16. The cylindrical rod member 12 is molded of plastic, or the like, and may be provided with holes or slots 18 extending diametrically through the central portion thereof to permit circulation of air to the hair when it is wound thereon. The tapered end portions 14 and 16 retain the hair on the rod and center the hair as it is wound up on the rod.

A retaining member 20 is in the form of an elastic strap made of rubber or other resilient material. One end of the strap is permanently attached to one end of the rod member 12, as indicated at 22. The other end of the retaining strap 20 is connected to a cap 24. As shown in FIG. 3, the cap 24 has a recess in the under surface in which is secured a metallic disc 26 made of a ferromagnetic material such as stainless steel or other noncorrosive but magnetically attracted metallic material. The disc 26 may be cemented or otherwise secured to the recess on the underside of the cap 24.

Normally the cap 24 hangs freely on the end of the strap 20, hanging to one side while the hair is wound on the rod 12. After the hair is wound in place, the retaining strap 20 is moved into retaining position to which it bridges the length of the rod 12 by moving the cap 24 into position opposite against the end of the rod 12. A permanent magnet 28 is mounted in a recess 30 in the end of the rod 12. The magnet is retained in place bya plastic liner or cover 32 which is cemented 'or otherwise held in position against the end of the rod member 12 after the magnet 28 is affixed.

By this arrangement, when the cap 24 is brought into position adjacent the end of the rod member 12, the metallic disc 26 is strongly attracted by the permanent magnet 28, causing the disc 26 to be held firmly against the surface provided by the liner 32. Strength of the magnet is such that the cap 24 is held firmly in place to hold the strap 20 in its hair restraining position. When the permanent wave rod is to be removed, the cap 24 can be easily moved laterally to free it from the attracting field of the magnet 28 and allowing the strap 20 to swing free of the rod 12.

It should be noted that the flexible strap 20 need not be under any significant amount of tension when the cap 24 is in position on the end of the rod 12. Thus it is very simple for the beautician operator to move the strap 20 and cap 24 into hair restraining position after winding the hair on the permanent wave rod.

What is claimed is:

l. A permanent wave rod for waving hair comprising a cylindrical member on which the hair is wound, an elongated flexible member secured at one end to one end of the cylindrical member, cap means including a magnetic material connected to the other end of the flexible member, and magnetic means mounted in the cylindrical member at the opposite end from the flexible member, the cap means being locked to the end of the cylindrical member by bringing it into proximity with the magnetic means, whereby the flexible member is connected at opposite ends to opposite ends of the cylindrical member.

2. Apparatus of claim 1 wherein the flexible member is elastic and slightly shorter than the length of the cylindrical member, the flexible member being stretched to make it taut when the cap is clamped by the magnetic means to the end of the cylindrical member.

3. Apparatus of claim 1 wherein the magnetic means comprises a permanent magnet mounted in the end of the cylindrical member.

4. Apparatus of claim 3 wherein the magnetic material in the cap means is a magnetic metal disc.
